To all whom t may concern.'

Be it known that I, ALBERT W. JONES, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Belt-Couplings, of which the following is declared to be a full, clear, and exact description.

This invention relates to belt couplings, and its principal object is to provide a two part, hinged together coupling having pointed members adapted to be driven into the belt and arranged in such manner that a more positive hold is obtained upon the belt, and the danger of tearing through the same is eliminated. This invention has particular reference to the type of belt couplings struck up from sheet metal, and having pointed ends or prongs formed on parallel united bars, and many attempts heretofore have been made to produce a satisfactory belt coupling of this type with but little success, because in some cases the pointed ends or prongs tend to tear or cut through the belt because of the pulling strain thereon, and in other cases they tend to cut the belt transversely thereof. With the use of a belt coupling made in accordance with the present invention, these objectionable features are wholly eliminated.

The invention consist-s in the several novel features of construction and arrangement hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawing, in which:

Figure l, is a plan of a blank from which one member of a coupling, embodying the present invention, is made; Fig. 2, is a plan of the blank after the pointed ends or prongs are bent up; Fig. 3, is a side elevation of one member, and a fragment of a belt, in position to be secured thereto; Fig. 4, is a plan of a complete belt coupling secured to a belt, only a fragment of the belt being shown, and Fig. 5, is a longitudinal section taken on line 5-5 of Fig. 4.

Referring to said drawing, the reference characters A, B, designate the two members which comprise the coupling; each of which comprises a plurality of parallel bars 6, spaced apart a distance .slightly greater than the width of the bars, and united near one end by cross bars 7, 7. The bars 6, are bent upon themselves at :zz-aa in Fig. 2, to form hinge knuckles 8, and in the completed coupling, the knuelrle's' of one member 6, lie bee7 tween those of the other and a pintle or pivot pin 9, extends therethrough to make the hinge joint.

At the ends of each bar are pointed members or prongs l0, 11, which are bent up along oblique lines, which extend at angles lying approximately at l5 degrees to the length of the bar. In use, said prongs extend through the belt, fragments of which are shown at C, D, along oblique lines, and the eXtreme points are clenched down, the points 11, being clenched between the cross bars 7, and the belt. Other prongs y or pointed members 12, are bent up from the side edges of the bars 6, at their ends, and said prongs l2, extend into the belt, but not necessarily through it, and act to prevent any lateral movement of the members A, B.

In constructing a coupling member, embodying the present invention, a blank is first struck up from sheet metal, and said blank may be as long as the sheet of metal. This blank is finally cut up into blanks of the size desired, by cutting away certain of the cross bars 7, the width of the blank being determined by the number of bars 6, between the cutaway bars 7. After the blank has been formed, the prongs 10, l1, are thereupon bent up along oblique lines, indicated at y-y in Fig. l, and the prongs 12, are bent up along lines parallel with the bars 6. Thereafter the bars 6, are bent upon lthemselves at ca and given the shape shown in Fig. 3. In this form, the coupling member is ready for attachment to the belt. In attaching it thereto, the end of the belt is placed in the angle between the two diverging portions of the coupling member, space being left between the eXtreme end of the belt, and the bend 8, for the reception of the pintle or pivot pin 9. The parts are then laid on an anvil, table or other hard object, and the prongs driven into and some through the belt, by hitting the upper bars with a hammer. By reason of the location of the cross bars 7 and prongs 11, the latter' strike the member at said cross bars and are clenched between them and the belt. The prongs 10, are also clenched upon the belt. After both coupling members have been attached to the belt, the bends or knuckles 8, of one are inserted between those of the other coupling member, and the pin 9, is inserted into the knuckle opening, thereby hingedly Connecting the two together.

It is to be observed that inasmuch as the direction. Furthermore, the pulling strain upon the prongs 10, is practically in straight lines, because the parts of thebars 6, on opposite sides of the Vcross bars 7, are not Voffset to any considerable extent, but the greater part thereof is inalinement.

More or less variation of the exact details of 'construction is possible without departing from the spiritof this invention; I desire, therefore, not to limit myself to the exact form of the invention shown and described, but intend `in the following claims to point out all of the invention disclosed herein.

I claim as new, and desire to secure by Letters Patent:

l, A sheet metal belt coupling member formed with parallel spaced bars, connected by cross bars and having clenchable prongs Yat their ends, bent into planes transverse to that of the bars, and oblique to lines running lengthwise thereof, the prongs at the respective ends of the bars being in alinement with each other.

. 2. A sheet metal belt coupling member, formed with parallel spaced bars connected by cross bars, and having clenchable prongs at their ends bent into planes approximately at right angles to that of the bars and at an angle of' approximately 45 degrees to a line running lengthwise of the bars, the prongs at the respective ends of the bars being in alineinent with each other.

3. A sheet metal belt coupling member,

Copies of this` patent mayV be obtained for formed with parallel, spaced and connected bars, each having one long and one short prong at its ends,"bent into planes approximately at right angles to that of the bars, the long prong at each end extending in an oblique direction to a line running lengthwise of the bar. Y

4. A sheet metal belt coupling member, formed with parallel spaced and connected bars, each having one long and one short prong at its ends, bent into planes approximately at right angles to thatl of the bars, the long prong at each end extending in an oblique direction to a line running lengthwise ofthe bar,'and the short prong extending lengthwise of the bar.

5. A sheet metal belt coupling member formed with parallel spaced and connected bars, bent upon themselves and formed with a long clenchable prong and a short prong at their ends extending in planes approximatelyvat right angles to that of the bars, and the long prongs extending in lines oblique to lines running lengthwise of the bars, the long prongs at one end of the bars being arranged to strike the bars near their other end, and clench thereunder when applied to a belt.

6. A sheet metal belt coupling comprising two companion coupling members, each consisting of a plurality of spaced, united barsl having a long clenchable prong and a short prong at their ends, bent into planes transverse to that of the bars and the long prongs extending in lines oblique to lines running lengthwise thereof, each member being bent into U-formation, with the long prongs clenched upon a belt, and the bent portions of' the bars of one member inserted between those of the other member, and a pintle extending through the openings of said bent ends.
